vaccine therapy in treating patients with liver or lung metastases from colorectal cancer

Conditions: Colorectal Cancer; Metastatic Cancer

Summary: rationale: vaccines made from a gene-modified virus and a person's white blood cells may make the body build an effective immune response to kill tumor cells. biological therapies, such as granulocyte-macrophage colony-stimulating factor (gm-csf), may stimulate the immune system in different ways and stop tumor cells from growing. combining different types of biological therapies may kill more tumor cells. purpose: this randomized phase ii trial is studying giving vaccine therapy together with dendritic cells to see how well it works compared to giving vaccine therapy together with gm-csf in treating patients with liver or lung metastases from colorectal cancer removed by surgery.

objectives: primary * compare 2-year disease-free survival of patients with completely resected hepatic or pulmonary metastases secondary to colorectal cancer treated with adjuvant vaccine therapy comprising vaccinia-carcinoembryonic antigen (cea)-mucin 1 (muc-1)- triad of costimulatory molecules tricom vaccine (panvac-v) and fowlpox-cea-muc-1-tricom vaccine (panvac-f) administered with autologous dendritic cells or with sargramostim (gm-csf). secondary * compare the rate and magnitude of immune response, as determined by enzyme-linked immunosorbent spot (elispot), in patients treated with these regimens. outline: this is a randomized study. patients are randomized to 1 of 2 treatment arms. * arm i: patients undergo leukapheresis to obtain leukocytes for generation of autologous dendritic cells (dc). patients then receive autologous dc loaded with vaccinia-cea-muc-1-tricom (panvac-v) vaccine subcutaneously (sc) and intradermally (id) on day 1 and autologous dc loaded with fowlpox-cea-muc-1-tricom (panvac-f) vaccine subcutaneously (sc) and intradermally (id) on days 28, 56, and 84. * arm ii: patients receive panvac-v sc on day 1 and panvac-f sc on days 28, 56, and 84. patients also receive sargramostim (gm-csf) sc into the same injection site once daily on days 0-3, 28-31, 56-59, and 84-87. after completion of study treatment, patients are followed for 2 years. projected accrual: a total of 72 patients (36 per treatment arm) will be accrued for this study within 2 years.
